Percentage of chitosaccharides liberated by incubation of the cell wall with purified glycoside hydrolases^a.

aData are ratios of liberated chitosaccharides to the total amount of chitosaccharides present in the starting cell wall material, and are mean percentages±S.E. of 3 independent experiments. Means for each treatment followed by a different letter are significantly different from each other (P<0.05). Enzymes were purified as described in Materials and Methods, except the β-1,4-endoglucanase from Megazyme which was used without further purification.
